The Telco PA 10 series are 1‑channel photoelectric amplifiers designed to work with LT transmitter and LR receiver remote sensors in thru beam and other optical sensing configurations. They provide signal conditioning, sensitivity adjustment, and output switching for remote photoelectric systems in industrial automation, conveyor sensing, and object detection applications. These amplifiers allow manual control over detection range and mode (light‑on or dark‑on), enabling flexibility for different target types and environmental conditions.
The PA 10 models differ by supply voltage, output type, and electrical characteristics. The PA 10 A variants are typically used with LT/LR series 101 sensors, while the PA 10 B versions pair with LT/LR series 100, 110, and 120 sensors. All models use an 11‑pole DIN socket connection and include LED indicators for power and output status. Manual sensitivity adjustment via an integral potentiometer and selectable long/short range mode help tailor performance to specific installation requirements.
